To celebrate its 190th anniversary, Yuengling is digging back into its own history books.

This month the nation's oldest brewery, D.G. Yuengling & Son, Inc., begins releasing a series of five limited-edition commemorative Yuengling Lager beer cans. Each month between now and April, a new can design will hit stores showcasing how the brewery's label has evolved since 1829, when it was originally called the “Eagle Brewery.”

Yuengling is also tapping a limited edition Bourbon Barrel Reserve beer, available Jan. 11, at its Pottsville, Pennsylvania, brewery. The beer was aged for 120 days in bourbon barrels stored in caves originally used for beer fermentation in the 1800's.

Visitors touring the brewery have been able to tour the caves, which had not been used in the making of beer since Prohibition. Now those who take the tour can taste the celebratory brew.

“We are incredibly proud to honor our history, like the hand-dug caves that were used for beer fermentation before refrigeration," said Wendy Yuengling, the brewery's chief administrative officer, and one of four daughters of owner Dick Yuengling who are involved in the business.

Yuengling, the largest craft brewery in the U.S., according to the Brewers Association, distributes to 22 states and brews at two other sites in Tampa, Florida, and Mill Creek, Pennsylvania. Earlier this year, the brewery brought to market its first new year-round beer in 17 years, Yuengling Golden Pilsner.

"We stay rooted in being a family-owned and operated company all these years," said Wendy Yuenging, "yet remain focused on the future and maintaining a disciplined business model around our core business, while continually looking at longer term consumer trends."

Two contests will give consumers a chance to win during the celebration. You can now post pictures involving Yuengling on social media with the hashtag #YuenglingGoodTimes for chances to win prizes including gift cards from Uber, StubHub, Uber Eats and online movie ticket site Atom Tickets.

And beginning in January, specially-marked 12-packs and 24-packs Yuengling Traditional Lager will have codes for prizes from Atom, Martin Guitars, StubHub and Uber.
